Angus Grimaldi is the helmsman and first aid officer aboard the Endurance in Tomb Raider. Born and raised in 'The Gorbals' of Glasgow, Scotland, one of the toughest places in the UK, he always felt a kinship with water and often built makeshift boats out of junk and taught himself to sail on the nearby river Clyde.
There’s nothing about sailing and water that Grim doesn't know, and he has sailed all the oceans of the world, which included stints working for the Merchant Navy where he met Conrad Roth. The two found a kinship and stuck together after their service, so when Roth purchased the Endurance he wouldn't trust anyone else but Grim at her helm.
